  Draw predicted future data with AI

New! Built-in AI function to predict the future AI comes standard on the GX/GP

 Future Pen

Use acquired data to predict future data, and display predicted future waveforms along with real time data on the trend monitor. Predicted future waveforms help you identify and deal with likely problems as soon as possible.

• Max. channels: 10
• Shortest recording interval: 1 sec.
• Prediction range: Recording interval x 60 points

You can set future alarms based on future data predicted by the future pen. You can check future alarm information in the Future Alarm Summary screen. Also, when a future alarm occurs, notification can be sent by external (digital) output or email. Because the future alarm information also includes the predicted alarm time, you can also identify the urgency

 Real time remote monitoring from a web browser

Through a Web browser you can monitor the GX in real time and change settings. You can easily build a seamless, low-cost remote monitoring system with no additional software.

Users have the ability to choose two different scan intervals on a single GX/GP system. This allows users the flexibility to measure various types of inputs with two different scan intervals in a single system. For example, this provides for efficient, simultaneous measurement of signals with slow fluctuations such as temperature, and fast-changing signals such as pressure and vibration. Modules can be assigned to measurement groups.

 MATH (including reports), and event actions

MATH function (/MT option)

Supports various kinds of math computation, including basic math and functions (square root, logarithms, trigonometry). Write formulas using variables for measured or computed data and save or display the results—this saves time and effort on post-processing. Create hourly, daily, monthly, and other reports with the Report function.

 Report creation and network functions (/MT option)

 Front panel door lock

The front panel door can be locked to prevent mishandling of the power switch or external media.

 Select file formats according to your application

For increased security, measured data can be saved in binary format. This format is very difficult to decipher or modify in traditional text editors or other programs. To enable easy and direct opening of the data in text editors or spreadsheet programs, choose text format. This allows you to work with your measurement data without dedicated software.

 Be confident that recorded data is saved

Measured and calculated data is continuously saved to secure, internal non-volatile memory. At manual or scheduled intervals, the files in memory are copied to the removable media. In addition, the files can be copied and archived to an FTP server

Because of the inherent reliability and security of non-volatile memory, the possibility of losing data under any operating condition or power failure event is extremely small

 Security enhancements

You can run the GX as an SLMP client, enabling writing of GX measured data to the PLC and writing of PLC data to communication channels. Requires the communication channel function (/MC option)

 Powerful tool for instrument performance evaluation testing (/E2 and /MC options)

Highly precise measured data from power measuring instruments (WT series power analyzers WT310E | WT310EH | WT332E | WT333E | WT500 | WT1800E | WT5000) can be acquired without loss of fidelity on the GX, and recorded and displayed alongside the GX's own measured data. This is ideal for performance evaluation testing because you can record instrument power consumption, temperature, and other phenomena simultaneously

 OPC-UA Server (/E3 option)

Data acquired by the GX can be accessed through Ethernet communication from a host system (OPC UA client). Writing from an upstream system to a GX communication channel requires the communication channel function (/MC option).

 Time synchronization with network time servers

GX uses SNTP protocol in client mode to acquire time information from a network time-server. This function allows any number of GX units within a facility to have precisely synchronized time; all units will record data with coordinated date and time stamp information. In addition, GX can function as a server, providing time data to other SNTP client units on the network.

  Strict security measures 

Advanced security function option (/ AS) corresponding to strict requirements for data management

SMARTDAC+ GX /GP/GM advanced security function option (/AS) provides safe and traceable data management in applications such as pharmaceutical manufacturing, biotechnology, health management and medical institutions. The advanced security function supports the strict requirements of US FDA 21 CFR Part 11, EU-GMP Annex 11 and other associated guidelines for data management. It also supports data integrity in accordance with ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) mentioned in PIC/S, WHO, MHRA and FDA guidance documents

 Secure electronic records

Measured data, settings, and operation logs, are saved to a single encoded binary file. Encoded data in binary format offers a high level of security because it cannot be opened in most text editors. If the data files are damaged or tampered with, SMARTDAC+ Standard Universal Viewer software will identify the nonconformity and notify the user according

 Electronic signature(data record signing) function

Measurement data can be displayed and confirmed on the GX/GP (only the data in the internal memory) or the SMARTDAC+ Standard Universal Viewer software, and an electronic signature can be applied to that data. Three levels of signature are available: operator, supervisor and quality control. The signature along with information such as pass/fail and comments can be saved to the data for review and audit.

  Logical security

Data integrity requires that the right users have access to the right information. SMARTDAC + can create users with various access privileges. Four main security levels (two separate administrator roles, user and monitor user). Up to 200 persons can be registered. Process owners/ system owners can be given access rights to functionality appropriate to their role. For the password, a minimum string length and a minimum policy complexity can be set. Centralized management of user names and passwords using servers on the network is possible through ActiveDirectory

 Audit trail function

The SMARTDAC+ operation log is saved to a file along with measurement data. When settings are changed, it is possible to record the reason for the change along with the setting change operation. In addition, checking the details of setting changes from "setting difference operation history" makes greatly reduces the data checking work during audits

 Validation documentation

Validation documentation (sold separately) is a validation protocol template that simplifies GX/GP/GM and SMARTDAC+ Standard system validation. The document is provided on the Yokogawa website as an MS Word file for easy editing.*
